The concerts will see Fletcher perform some of her favourite songs, while also chatting about her career, with as yet unannounced surprises to feature.

The musical theatre star's credits include Les Miserables, Chitty Chitty Bang Bang, Mary Poppins and most recently as Wednesday Addams in the UK tour of The Addams Family. She also has a successful YouTube channel with over 650,000 subscribers.

Fletcher said: "Being alone on stage without a character to hide behind has always terrified me but I've always been one for facing my fears. Whilst I'm nervous I'm secretly quite excited that I get to sing all the songs I may never get to sing professionally. Songs only my shower, and neighbours, have heard me sing so this concert will hopefully be something very unique!"

Fletcher is also a bestselling author, with both fiction and nonfiction titles topping charts. Her third novel, When The Curtain Falls is scheduled to be released in July 2018.
